【摘要】 介绍了基于二进小波变换的图像插值方法,并且对各种插值方法在不同域中的结果作了比较,主要是对最近邻插值、双线性插值和双三次插值几种方法在空间域、正交小波域、二进小波变换中作了比较。试验结果证明,基于二进小波变换的图像插值效果比较好,值得进一步深入研究。更多还原

【Abstract】 This paper introduces a method of image interpolation based on dyad ic wavelet transform, and compares interpolation methods in different domains. M ostly this paper compares the nearest interpolation, bilinear interpolation, cub ic interpolation in spatial domain, wavelet and dyadic wavelet transform. The ex perimental results show that the method of dyadic wavelet transform is the best one and this is worth of researching in depth.更多还原
